Texas Instruments  LMK00334RTVTQ1

The LMK00334-Q1 device is a 4-output HCSL fanout bufferintended for high-frequency, low-jitter clock, data distribution, and level translation. The inputclock can be selected from two universal inputs or one crystal input. The selected input clock isdistributed to two banks of two HCSL outputs and one LVCMOS output. The LVCMOS output has asynchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00334-Q1 operates from a 3.3-V core supply and three independent
3.3-V or 2.5-V output supplies.

The LMK00334-Q1 provides high performance, versatility, andpower efficiency, making it ideal for replacing fixed-output buffer devices while increasing timingmargin in the system.
